Threads and Runnable Objects

• The java.lang.Thread class is the base for all objects that can behave as threads
• Most of the time Threads are conceptually just an activity. Such activities need a focal poing (i.e., what code they are to run)
• All Threads need a handle to an object (a Runnable object), whose run() method it will "execute in"
• To facilitate this protocol, Java supplies a simple interface java.lang.Runnable
